This section provides you with the information needed to physically and electrically install the<br />
<strong>EFIS</strong>-<strong>D100</strong>.<br />
Selecting a Remote Compass Module Location<br />
Finding a good location for the EDC-D10A<br />
remote compass module is critical to an<br />
accurate <strong>EFIS</strong>-<strong>D100</strong> heading display. Keep<br />
in mind that calibration can compensate for<br />
small static magnetic fields superimposed<br />
upon the earth’s field; it cannot take<br />
into account dynamic effects like<br />
AC currents, non-constant DC<br />
currents and non-stationary ferrous<br />
material (e.g., an electric turn<br />
coordinator). Use the following<br />
suggestions to help you find a good<br />
location for your EDC-D10A.<br />
Keep the EDC-D10A away from<br />
any source of magnetic fields<br />
(such as electrical equipment and currentcarrying<br />
wires) and ferrous material.<br />
Move a handheld compass throughout the<br />
space surrounding your location to get a rough<br />
idea of the suitability of your chosen location.<br />
If the needle deviates significantly from<br />
magnetic north in any given area, that location<br />
would not be ideal for the EDC-D10A.<br />
The EDC-D10A can be mounted anywhere in<br />
the aircraft (away from magnetic interference)<br />
such that its pitch is as close to that of the<br />
<strong>EFIS</strong>-<strong>D100</strong> as possible. It does not need to be<br />
directly along any axis of the <strong>EFIS</strong>-<strong>D100</strong>. It<br />
should be mounted with the long axis<br />
parallel to the wings, the electrical<br />
connector facing toward the front of the<br />
plane, and the mounting tabs on the bottom.<br />
The bracket used to hold the EDC-D10A<br />
must hold the EDC-D10A at the same pitch,<br />
roll, and yaw as the <strong>EFIS</strong>-<strong>D100</strong> with respect<br />
to the airframe. We recommend that you use<br />
an electronic level, if available, to make<br />
sure the EDC-D10A is aligned with the<br />
<strong>EFIS</strong>-<strong>D100</strong> to better than 1 degree.<br />
